For an implant prosthesis to function permanently and well in the oral cavity, it is necessary to consider various biomechanical factors. 2 Esposito et al. reported that occlusion-induced overloads are associated with increased morbidity and poor durability of dental implants. In order to obtain appropriate occlusal contacts in prostheses, it is important to determine the reproducibility of occ...

One of the most important steps is accurate impression making for fabrication of fixed partial denture. The two different putty-wash techniques that are commonly used are: (1) Putty-wash one-step technique, (2) putty-wash two-step technique. A uniform wash space is needed for an accurate impression. Nissan et al recommended the use of two-step technique for accurate impression making as there i...

Impression techniques for implant restorations can be implant level or abutment level impressions with open tray or closed tray techniques. Conventional implant-abutment level impression techniques are predictable for maximizing esthetic outcomes. Restoration of the implant traditionally requires the use of the metal or plastic impression copings, analogs, and laboratory components. Simplifying...

PURPOSE This study compared polyvinylsiloxane with polyether in handling dental impressions. MATERIALS AND METHODS Each participant (N = 39) made four impressions, each a combination of pickup and reseating techniques with polyether or polyvinylsiloxane, of one implant cast representing a specific clinical situation (tooth gaps, limited residual dentition, or edentulous jaw). Handling of impr...
